[0002] The presser foot is a component that applies pressure on the surface of the sewing material. According to the performance of the sewing machine, the presser foot is divided into a flat sewing machine presser foot, an overlock machine presser foot, and a special machine presser foot. According to its function, the presser foot is divided into a common presser foot and a special presser foot. There are many types of special presser feet, such as hemming presser feet, feeding presser feet, double needle presser feet, etc.

[0028] In one embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the limiting assembly includes a slide groove 6, which is opened on one side of the second fixing bar 3. A threaded hole 7 is opened in the upper middle part of the first fixing bar 2. A bolt 8 is threadedly connected to the threaded hole 7. The bolt 8 is rotated in the threaded hole 7 and then moves away from the slide groove 6, so that the second fixing bar 3 can slide in the first fixing bar 2.
[0029] In one embodiment, Figure 1 As shown, the moving assembly includes a motor 9, and the motor 9 is fixedly connected to one side of the support bar 1. A first limiting groove 10 is provided on the side of the support bar 1 away from the first fixed bar 2. A threaded rod 11 is fixedly connected to the output end of the motor 9. The threaded rod 11 is rotatably connected to the first limiting groove 10, and the threaded rod 11 is threadedly connected to the inside of the slider 4. By starting the motor 9, the threaded rod 11 is driven to rotate inside the first limiting groove 10, and the threaded rod 11 is threadedly connected to the inside of the slider 4, so the rotation of the threaded rod 11 will drive the slider 4 to move laterally in the first limiting groove 10, and the slider 4 drives the presser foot 5 to move at the same time.
[0030] In one embodiment, Figure 1 and Figure 4 As shown, the adjustment component includes a second limit groove 12, and the second limit groove 12 is opened on the side of the slider 4 away from the support bar 1. A bidirectional screw rod 13 is rotatably connected in the second limit groove 12. The threads at both ends of the bidirectional screw rod 13 are threadedly connected to the inside of the presser foot 5. By rotating the bidirectional screw rod 13, it drives the second limit groove 12 to rotate. Since both ends of the bidirectional screw rod 13 are threadedly connected to the inside of the presser foot 5, the rotation of the bidirectional screw rod 13 will drive the presser feet 5 to move closer or farther away from each other.
[0031] In one embodiment, Figure 1 As shown, mounting strips 14 are provided on both sides of the top of the second fixing strip 3, so that the entire device can be installed.
[0032] In one embodiment, Figure 2 As shown, the length of the slide groove 6 is smaller than the length of the bolt 8, and a first turntable 15 is provided at one end of the bolt 8 away from the slide groove 6. The first turntable 15 facilitates the rotation of the bolt 8. The length of the slide groove 6 is smaller than the length of the bolt 8, so that the bolt 8 can be low-connected with the inside of the slide groove 6 to increase the resistance.
[0033] In one embodiment, Figure 4As shown, the second limiting groove 12 does not contact the threaded rod 11 , and a second rotating disk 16 is provided on one side of the bidirectional screw rod 13 , so that the rotation of the bidirectional screw rod 13 is facilitated by the second rotating disk 16 .
[0034] In one embodiment, Figure 1 and Figure 4 As shown, the middle part of the presser foot 5 is lower than the two sides, so that the presser foot 5 can press the material.
[0035] The working principle of the utility model is as follows: the above-mentioned embodiment discloses an independent presser foot that is easy to move horizontally, wherein the entire device is installed through the installation strip 14, and then according to actual needs, the first rotating disk 15 is rotated to drive the bolt 8 to rotate at the threaded hole 7, and then away from the slide groove 6, so that the second fixing strip 3 can slide inside the first fixing strip 2, so as to adjust different heights, and then the first rotating disk 15 is rotated again to drive the bolt 8 to approach the slide groove 6, and then the bolt 8 and the inside of the slide groove 6 abut against each other to increase resistance, so that the first solid strip 2 is limited and fixed, and then the first rotating disk 15 is rotated again to drive the bolt 8 to approach the slide groove 6, and then the bolt 8 and the inside of the slide groove 6 are abutted against each other to increase resistance, so that the first solid strip 2 is limited and fixed, and then the first rotating disk 15 is rotated again to drive the bolt 8 to move closer to the slide groove 6, and then the first solid strip 2 is limited and fixed. The second turntable 16 is moved to drive the bidirectional screw rod 13 to rotate in the second limiting groove 12. Since both ends of the bidirectional screw rod 13 are threadedly connected to the inside of the presser foot 5, the rotation of the bidirectional screw rod 13 will drive the presser foot 5 to move closer or farther away from each other, so as to adjust. After adjusting to a suitable distance, the motor 9 can be started according to the working process to drive the threaded rod 11 to rotate in the first limiting groove 10. The threaded rod 11 is threadedly connected to the inside of the slider 4, so the rotation of the threaded rod 11 will drive the slider 4 to move horizontally in the first limiting groove 10, and the slider 4 drives the presser foot 5 to move at the same time.
